I have been messing about with MS Power Point.
Done OK but the files are huge.
I get PP stuff by email and the files are much smaller and also I
notice when saved, have a different icon.
Why is this and can I make the files smaller somehow?
I have windows XP.
You need to start with smaller images. By smaller, I mean the file-size of
each picture needs to be made smaller. Each picture will add to the size of
the PPT file. For example, if you've inserted 4 pics, each originally 500K,
the resulting PPT will be over 2MB.
How large (file size) are the images you're inserting into your slide show?
Could be the way it is saved.
or the open document format. they all produce different size files.

I should have added that the solution to this is
to just look at the extension on the file
type on the smaller files, eg .zip, .ppt, etc.
Googling will tell you what kind of file it is and
how it was produced.
OK, here's what I just tried:
I saved a 6.7Mb ppt file and a 3.5Mb ppt file as pps files and they
saved with a file size within a few Kb of the original. So saving them
as pps files does not condense them at all. That makes sense, since
you can simply change the file extension from ppt to pps (and vice-
versus) to create slideshows and/or normal presentations. It's the
same file, the extension just tells PowerPoint how to open it.
The next thing I tried was this:
I exported all the slides as jpg files (Save as *.jpg) which creates
a folder full of jpgs, one jpg for each slide.
I then ran a macro to create a new PowerPoint document made up of the
jpgs The macro can be found here:
This created PowerPoint files of 2.3Mb from the 6.5Mb file and 1.7Mb
from the 3.5Mb file.
So basically, I was able to condense the files by about 1/3 to 1/2 by
exporting the slides as jpgs and then rebuilding the presentation from
those same jpgs.
Hope that helps!
In addition, I just tested my earlier process with jpgs I already had
on my system.
I inserted 3 jpgs into a powerpoint document. Each jpg was
approximately 500K. The filesize of the resulting ppt file was 1.6Mb.
I then exported the jpgs (Save as...*.jpg) and it created 3 jpgs of 85
- 90 Kb.
When I built a ppt with these new jpgs, the file size was 323Kb.
So, take your huge file, export all of the slides via Save as *.jpg,
then rebuild the ppt via the macro and you will greatly reduce the
And the fastest, easiest way to do this in Windows is with the Image
Resizer for Windows program. MS made a version for XP that doesn't work
in Win7. But I found and installed a Win7 version from Brice Lambson
that you can get here:
Looks/feels/works the same way it did in XP. It installs into the shell
and after installation a right click on the file name in windows
explorer adds the resize option to the action list that will open. Very
intuitive and effective.
I use it too. You have to wonder why it isn't just a
standard part of the Windows package by now. I
guess it's because Windows still isn't as userfriendly
and neat of a package as windows.
Speaking of which, I recently got a chance to try an
iPad. Boy was I shocked. Using google maps on there
I was able to move so smoothly and quickly with the map
being constanly refreshed that I was shocked. Using my
finger I went from my home in central NJ all the way to
Lake George, NY with resolution set at just a few miles.
I was just scrolling to see how fast it could keep up.
In no time I was at NYC, so I just kept scrolling up the
Hudson River, and it just kept going. Within about 2
minutes I was at Lake George, seeing everything in
between scroll by. Other web apps performed with
blazing speed too.
That was with a wireless G connection. With my wired
connection and a one year old high end desktop PC,
no way it can do that. I don't know if the difference is the
OS or the hardware, but it's amazing. Even more so
that they can do it on a small battery powered device.

Then you need to reduce them in Photoshop to a smaller size. Try 72dpi and
as small an image size as will show up correctly in the PPT. Also slide the
"quality" slider down to 6 or 4 when you make the JPEG. This can have a
dramatic effect on file size.
For the serious or semi-serious digital photographer, or someone when
does a lot of media generation, a digital image editing program, such as
photoshop is clearly a useful, important and flexible tool. However, it
takes a certain amount of time to become familiar with how to use the
program, even the simpler versions. Many folks have made careers from
teaching photoshop courses. It is not exactly a user friendly program
for the casual recreational PC user. Using a digital image editing
program to reduce the pixel content of an image requires reasonable
knowledge of what final specifications you're aiming to achieve, and a
goodly number of mouse clicks unless you write a macro for subsequent
image reduction tasks (and writing photoshop macros that work
effectively takes time to learn).
For the occasional user who knows nothing about pixel density, number of
colors, image dimensions, lossy versus lossless compression algorithms,
ultimate file size, etc, etc, the beauty of the windows image resizer is
that the entire process only takes 2-3 mouse clicks and requires no
technical knowledge at all to successfully reduce a large image file to
a much smaller file that sill looks excellent on a computer monitor. It
probably will suffice for the great majority of users who want to reduce
2-8 Mb image files to a few hundred Kb when uploading image files to
their own web pages, or as attachments to friends and family, or for
producing effective power point files that aren't bloated. You don't
need a Lamborghini to get yourself into town to run errands.
To check fhe file size and picture quality in Photoshop, go to Edit > Image
You can change those parameters in the same dialog box.
Screen resolution (72dpi) is all that's needed for computer-screen viewing.
Anything higher than that is a waste of disk space on a file that's meant
for online viewing.
Anything higher than 72 dpi is meant for printing. 300 dpi is a standard
resolution for litho, but even that tends to get dumbed-down to closer to
150dpi in production.
The online tutorials you can find on YouTube are better.
re"...when saved, have a different icon"
What is the 3 or 4 letter extension on the file name?
ppt or pptx was saved as a "standard" PowerPoint document (the x being
for Office versions 2007 and beyond).
Open it and you'll have access to the individual slides.
pps or ppsx was saved as a PowerPoint slide show (the x being for
Office versions 2007 and beyond).
Open it and and the slide show will run automatically.
They may have been saved as a pdf document, which would typically be
Open it and you'll see the individual slides, but they won't really be
PowerPoint slides. They're actually individual pages in a PDF
If it's not one of those 5 extensions, tell us what it is and we'll
see what else we can offer.
